You'd be doing yourself a disservice to not stay at this place. The design, the location, but most importantly the views are to die for. Bedroom and bathroom are very comfortable and perfectly sized.
The place is very easy to find on Uber and towers above the skyline. Train station is a bit of a walk, but otherwise very doable. Traffic can get exceptionally backed up, so plan your trip(s) accordingly.
Check in and check out were very easy, and the staff that work the building were more than friendly.
If / when we return to Bangkok this will be our first choice of stay.
